METHOD 0F MAKING CULINARY PACKAGES.

Original application tiled December 29, 1925, Serial No. 78,134. Divided and this application tiled Hay 10,

t 1926, Serial No. 108,016. Renewed November 16, 1927.

This invention relates to the methodof making culinary packages and 1s a division of co-pending application Sr. No. 78,134, filed December 29, 1925, and hasv for an ob- 5 ject to provide a new and improved method of constructing a bag for containing acommodity both for merchandising and culinary use, which commodity expands or swells during its use as a culinary device.

A further object of the invention 1s to provide-improved method of making a bag which comprises a rolled fabric, the. overlapping edges of which are not unlted .and closed upon opposite ends of the contained commodity by metallic or like bands or sleeves which embrace and retain the gathered fabric.

Vith these and other objects in view, the

invention comprises certain novel stepsin the method of constructing the bac' as will be hereinafter more fully described and claimed.

In the drawings:

Figure l is aview in side elevation of the completed bag or package.

Figure 2 is a transverse sectional view through the package as indicated by line 2--2 of Figure 1.

Figure 3 is a view more or less diagrammatic showing the method of constructlng the package.

Like characters of reference indicate corresponding parts throughout the several views.

The present invention comprises a method of making a bag especially adapted for marketing a commodity, which said bag with the contained commodity is used by the consumer in culinary pursuits, such for instance as tea which may be marketed in the bag and, while still contained in the bag, immersed in water to provide an infusion.

The bag is constructed from a strip 10 of fabric material loosely Woven which, according to the present ractice, will be the material ordinarily re erred to as cheese cloth, but it is to be understood that the invention is in no way limited to the particular Weave or nomenclature of the fabric.

The strip of fabric 10 is moved in the directionindicated by the arrow in Figure 3 by any approved means, manually or mechanically, and during such moving the commodity, as for instance the tea, is deposited upon the strip in spaced masses as indicated at 1l. This strip of material 10 will have one edge which is relatively nonstretchable and this may be previously supplied to the strip in the manner well known 1n the art and referred to as selvage, but preferably this non-stretchable edge will be provided by means of over-seeming, indicated at 12, which is applied directly to the strip as it moves along by aproperly positioned sewing machine, conventionally shown at 13. The edges of this strip 10 are drawn together and more or less rolled with the non-stretehable edge 12 outermost, overlapping the inner edge 13, yshown at Figures 2 and 3, for such a distance that the expansion of the material within this rolled and overlapped strip will not effect a separation of the edges for discharging the material contained. The edge 12 also serves as a tension so that the stress ordinarily applied to one or both edges of the completed bag tends to hold this non-stretchable edge in tension upon the under folded edge.

As the strip advances, the part intermediate the deposited masses of commodity are drawn together and const-ricted as indicated at 14 in Fi ure 3, and bands-15 are place or closed a out said constricted portion, spaced apart. Before closing one of the bands 15, a string or cord 16is slipped thereunder to which is previously or afterward attached a tag indicated conventionally at 17 by Which the commodity contained in the bag may be identified and which together with the cord 16 serves to handle the completed bag shown at Figure 1. The completed bag is then severed from. the advancing strip by a knife 18,- mechanically or manually actuated, so that the constrlcted portion is severed intermediate the spaced bands 15 whereupon the bag is not only completed but severed and wholly independent from the strip as indicated.

It is obvious that the bag will normally be handled by the cord 16 which exerts pressure of the contained material thereon and serves to draw the non-stretchable edge 12 in taut relation over the under folded edge holding it against the contained pressure of the material, but nevertheless, when deposited in a receptacle for use and the tension released, permits the sliding of the inner edge of the outermost folded edge for expansion.

lVhat I claim to be new is:

1. The method of making a commodity aekage. consisting in depositing a connnodity in predetermined quantity in spaced rclation upon a strip of fabric, rolling the fabric to roll the commodity within the rolled fabric, with one edge rolled under the other edge, maintaining the rolled strip against lateral distortion, forming about the roll intermediate the quantities of commodity bands to hold the roll in constricted, closed condition and severing the units formed by the bands.

2. The method of forming a commodity bag consisting in depositing upon a strip of fabric material having one relatively nonstretchable edge, quantities of commodity in spaced masses, rolling the strip of material to roll the commodity masses therein with the non-stretchable edge overlapping theopposite edge of said strip, constricting the rolled 'fabric intermediate the masses of commodily` placing about the constricted portion spaced bands, and severing intermediate the spaced bands.

3. The method of producing a commodity bag consisting in depositing upon a strip of fabric material having one relatively nonstretcliable edge commodity in spaced masses, rolling the strip about the masses of commodity with non-stretchable edge outermost and overlapping the other edge drawing the rolled strip together iutermedlate the masses of connnodity, placing about said drawn together parts spaced bands, under one of which before closing a cord is inserted, and severing intermediate the spaced bands.

4. The method of producing a commodity bag consisting in moving a strip of fabric material in proper relation to a sewing machine to produce an over-seeming along one edge, producing a relatively non-stretchable edge, depositing upon the moving strip commodity in spaced masses, rolling the strip with the non-stretchable edge outermost and overlapping the opposite edge, drawing together the rolled strip intermediate the masses of commodity, securing the drawn together parts by means encircling said parts and spaced apart, and severing the drawn together part intermediate said holding means.

In testimony whereof I ax my signature.
